Kew Gardens marks one of the final stages of the State Visit
The scientific and conservation efforts between the UK and Japan where high on the agenda when His Majesty the Emperor of Japan toured the Royal Botanic Gardens in Kew.
The recent event celebrated the rich history of collaboration of Kew with Japan and the Japanese Royal Family.
The tour of Kew, which marked one of the final stages of the State Visit, began in the historic Temperate House where the Emperor was greeted by Richard Deverell, OBE, Director of RBG Kew.
‘We were honoured to welcome His Majesty the Emperor to the Royal Botanic Gardens, Kew,’ explains Richard.
‘We have had a longstanding and close relationship with Japan which can be seen through beautiful structures in our landscape as well as in our living collections, economic botany and art collections.’
‘In 2021 we celebrated the relationship through a wonderful month-long Japanese festival in the Temperate House.’
‘We are especially proud too of the scientific links we have through our Millennium Seed Bank in Wakehurst which includes important conservation work under the Global Tree Seed Bank Programme, amongst other achievements.’
Conservation and art on display at Kew
Inside the Victorian glasshouse, the Emperor was presented with material from Kew’s Millennium Seed Bank at Wakehurst, which is home to the world’s largest collection of more than two billion wild plant seeds from more than 97 countries.
Dr Elinor Breman, Senior Research Leader at the seed bank, highlighted several collections which included seeds banked from trees that survived the Hiroshima atomic bomb.
These are now being grown under the Global Tree Seed Bank Programme with the University of the Ryukyus and Kyushu University for conservation in Hokkaido, Kyushu and Okinawa.
The Emperor was then presented with five artworks by Kew’s resident botanical illustrator Masumi Yamanaka, who has worked at Kew since 2006.
Their detailed illustrations aid scientific efforts to describe new species of plants. The paintings on display were: Japanese Pagoda Tree, Tulip Tree, Miracle Pine, Indian horse chestnut (Summer), and Indian horse chestnut (Autumn).
The tour continued with the Emperor meeting Paul Denton, Head of Visitor Programmes and Exhibitions and British artist Marc Quinn.

Marc’s metallic sculptures are prominently displayed in the Temperate House and across Kew Gardens as part of the summer programme Marc Quinn: Light into Life.
A key element of the exhibition includes Held by Desire in the Temperate House – two five metre tall bonsai trees cast in bronze which are surrounded by life-sized sculptures and specimens from Kew’s own collection of bonsai trees.
Kew Gardens’ collection of bonsai trees
The Emperor then met horticulturist Richard Kernick, who maintains Kew’s collection of about 60 bonsai trees. One of them is 180 years old and which can be admired in Kew’s Bonsai House.
‘Often thought to be dwarf forms of trees, Bonsai are, in fact, miniature trees that have been expertly pruned and shaped to prevent them from growing to their natural full size,’ says Richard.
‘This intricate and precise art form transforms trees into tiny living treasures. A living bonsai is a never-finished artwork that usually outlives its artist. Inheriting a tree is like being a rung on a ladder – there are often many rungs behind and hopefully many rungs ahead.’
